For architectures I don't have I rely on users to provide feedback.
On 64 bit Windows, the key is not being redirected by Windows.
I assume that this is dependent on how one accesses the key.  Perhaps
redirection is supported through certain APIs and not others.  At any rate,
I am assuming from your answer that R is not involved in such redirection
and am adding code to handle both sets of keys.
